Clients of libpurple don't have to use all the protocols, or have them as options. Looking at the QuteCom wiki and various documents I could find, it looks like they're using libpurple for specific backend/frontend handling and their client doesn't support other protocols.

From a quick search for ICQ/Jabber in the bug tracker, it looks like it should work or at least have worked at some time. Unfortunately I got no feedback at #qutecom.

all the links I could find recently indicated that qutecom should work with other protocols as did wengo. I'll try IRC and see if I get anything, if not I'll just have to accept this as the answer :P
